Stadium Events is one of the world’s first exercise focused gaming titles. It was released to an extremely small test market in the U.S. in 1987. The following year, Nintendo bought the rights to the fitness mat that came with the game and supposedly all titles related to it were destroyed. The mat was then renamed the Power Pad.

According to Kotaku, a sealed box version of Stadium Events sold for $41,300. This copy of Stadium Events, while still in the box, had its plastic seal broken.

Hamm wasn’t able to afford the game since he just opened his store. The woman intends on selling it on eBay in a few weeks.
